If it's a daily (and if you can live with it) then I would say don't respray the car. It will get scratched soon, and then it's not perfect, and it'll mess with your head.

Also if it's a daily just do some DIY carby mods (check DIY section) so it goes a little better. Rear disc brake conversion isn't hard, but also isn't necessary unless you're planning to go tracking or on long spirited drives. Suspension is a great option IMO because even if you sell the car you can put the standard parts back on and move the good ones to your new ride (within reason).
